OmniFaces 2.x requires CDI. See also Download section of OmniFaces homepage: OmniFaces 2.x Required: Java 1.7, JSF 2.2, EL 2.2, Servlet 3.0 and CDI 1.1 Optional: BV 1.0 Tomcat as being a barebones JSP/Servlet container doesn't ship with CDI out the box.

What does omnifaces JNDI.lookup not have a checked exception for NamingException?
Is there a way of just returning null for non-existant variables instead? It does that for NameNotFoundException. The problem was here not in OmniFaces, but in the environment, which was GlassFish 4.1 in your specific case. It unexpectedly wrapped the NameNotFoundException in another NamingException, hereby causing the underlying NameNotFoundException...
Adding composite component programmatically
jsf,composite-component,omnifaces
The includeCompositeComponent() returns an UIComponent instance representing the composite implementation. UIComponent composite = Components.includeCompositeComponent(someParentComponent, libraryName, resourceName, id); All of its attributes are available as a Map by UIComponent#getAttributes(). Map<String, Object> attributes = composite.getAttributes(); You can use Components#createMethodExpression() to create an EL method expression. Assuming that you intend to specify #{bean.complete},...
How can I embed an SVG image using JSF/OmniFaces/PrimeFaces?
The <o:graphicImage> sets a default content type of image, but your browser apparently didn't swallow that for SVG images. As per this commit, I've for OmniFaces 2.1 added SVG support for <o:graphicImage dataURI="true"> and I've added a new type attribute which allows you to explicitly specify the image type via...
Enum properties are not retrieved by OmniFaces in Spring / JSF projects
jsf,tomcat,el,jsf-2.2,omnifaces
This is more related to EL than to JSF/Spring/OmniFaces. The Apache EL implementation as used by Tomcat is indeed quite restrictive as to reserved keywords. So is for example #{bean.class.name} (as in, print bean.getClass().getName()) possible in Oracle EL implementation as used by GlassFish, but not in Apache EL implementation as...
o:graphicImage throws java.lang.IllegalArgumentException: argument type mismatch
jsf,jsf-2.2,omnifaces,graphicimage

So, most of standard types...
Can't get Omnifaces resource handlers to work: Unable to find resource
UnmappedResourceHandler doesn't support resource libraries. It's mentioned in the javadoc and showcase. And the following CSS file reference (note: the library is not supported by the UnmappedResourceHandler! this is a technical limitation, just exclusively use name): <h:outputStylesheet name="css/style.css" /> The technical limitation is that it's otherwise not possible to relatively...
java.util.ServiceConfigurationError when running tests using arquillian+omnifaces

After trying to run a built war and running it on Wildfly standalone, I managed to narrow the problem to Arquillian, after testing Arquillian+Glassfish embedded and running without problems, I figured the issue was Arquillian+Wildfly, some more googling around and I found similar issues that were related to using Wildfly...
JSF CDI @Named + isAnnotationPresent + @CustomSecurityAnnotation

Does UnmappedResourceHandler work for library versioning?

Navigate to previous page with JSF
You need the page id you're navigating from somewhere. At first look, keeping it in Session seems to be a good idea, however, this could remain in coflict if you're navigating in multi-tab (sharing same Http Session through different browser tabs). Having said that, the most proper solution for your...
In Primefaces picklist, how to find that an item is moved from TARGET to SOURCE, Using Omnifaces Converter
jsf,jsf-2,primefaces,omnifaces
This is how I got it worked for me. In the implementation of the Omnifaces ListConverter, the getAsObject method is using the list to find the value and update the target and source of dualList. NOTE: you will get either a new value added in target (List=".getSource") or a new...
Auto Code Completion on Eclipse Kepler for Omnifaces o:importConstants
eclipse,java-ee,jsf-2,enums,omnifaces
Basically, this requires a custom Eclipse plugin which recognizes the <o:importConstants> tag and prepopulates the autocomplete menu. As of now, no such plugin exist and there are as far as I know no plans (at least not from our side) for writing IDE specific plugins for OmniFaces tags/components. I must...
Implement instead of icon in of
jsf-2,primefaces,omnifaces,megamenu,graphicimage
As far as I understand, you was trying to use something like: <p:menuitem ... icon="#{imageStreamer.getImage(23)}" /> This indeed won't work. It would be evaluated immediately when the renderer obtains it. This is also not how <o:graphicImage> works. It postpones the evaluation to the moment the browser actually needs to request...

omnifaces starting before openwebbeans 1.5.0?
OmniFaces needs to change the check code as it is non-portable. The CDI Specification does not define that the BeanManager nor any Context needs to be available in a ServletContainerInitializer. This is highly depending on the target environment and integration scenario and thus highly non-portable. This is also a regression...
How to trigger Components#includeCompositeComponent() call?
jsf,composite-component,omnifaces
You need to trigger it during the view build time. The postAddToView event listener approach must work. Perhaps you did it the wrong way. Here's a kickoff example: <h:panelGroup> <f:event type="postAddToView" listener="#{bean.build}" /> </h:panelGroup> With this, assuming that you have a form.getType() of form1 and thus want to include <my:form1...

This is a bug in MyFaces. I can't tell which MyFaces version exactly contains the fix, but I can tell that this construct works fine in at least MyFaces 2.1.12. However, upgrading MyFaces in WebSphere might not be a trivial task (technically and bureaucracy). Your best bet is to tell...
Facelets error page works during ajax request with FullAjaxExceptionHandler, but does not evaluate EL during synchronous request
jsf,error-handling,web.xml,omnifaces
The <error-page><location> must match the FacesServlet mapping in order to get FacesServlet to run on the error page too during an exception on a synchronous request (which doesn't use ViewHandler#renderView(), but RequestDispatcher#forward()). Alter the mapping accordingly: <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>*.xhtml</url-pattern> </servlet-mapping> Using /faces/* (and *.faces) is soo JSF 1.0/1.1.

EL expressions in Omnifaces CDN resource handler not resolved in Wildfly 9
It's consequence of a bugfix in Weld implementation of WildFly 9. As per issues CDI-525, WELD-1941 and WFLY-4877, the CDI spec appears to be not consistent with JavaBeans specification as to default managed bean name in case the unqualified classname starts with more than two capitals. CDI spec merely stated...

Override Omnifaces Validation Message with JSF message-bundle?
validation,jsf,omnifaces,message-bundle
This is currently not supported by OmniFaces validator components.

I reported an issue so that the OmniFaces guys are noticed about it and may implement it...
Error Omnifaces o:validateOrder with Rich Faces Calendar component
The <o:validateXxx> components are sensitive to their location relative to the target input components. This is very useful to prioritize validation depending on component's own converter and validators. When placed before the target input components, then they will validate the raw unsubmitted values, and they will run before any of...
Avoid rendering empty byte array with
jsf,omnifaces,graphicimage,conditional-rendering
You'd really better not call that image streamer method in a rendered attribute. It's invoked multiple times during the JSF lifecycle, hereby inefficiently getting the image bytes from the DB every time. The model also doesn't look right in first place. I suggest to change the model. Make the image...

@ViewScoped is tied to a JSF view, however durig a JAX-RS request, there's no means of a JSF view anywhere. There's no JSF view being restored during a JAX-RS request as the JAX-RS request is not initiated by submit of a JSF <h:form> which holds information about the JSF view...
Disable RestorableViewHandler in Omnifaces
It's not possible to disable it without hacking around in OmniFaces source. As per issue 92 this has been fixed by letting <o:enableRestorableView> setting an application wide attribute once it's been used somewhere, so that the RestorableViewHandler can decide whether to try to restore the view or not. Note that...
